At Container One, we build container offices from New 1-Trip shipping containers for contractors, farmers, industrial operations, and businesses that need workspace where the work happens. Each unit arrives with insulation, HVAC, electrical systems, lighting, windows, doors, and security features — ready for furniture and immediate use.
Our shipping container offices start at 160 square feet (20ft) for site supervisors and small teams, scaling to 320 square feet (40ft) for multi-workstation setups with meeting areas and storage. Unlike rented office trailers, you own the asset. Unlike traditional construction, you can relocate as projects move. Built from Corten steel, these portable office containers last 25 or more years with minimal maintenance, even with regular relocation.

Frequently Asked Questions About Shipping Container Offices
What is a shipping container office?
A shipping container office is a standard ISO shipping container, typically a 20ft or 40ft New 1-Trip unit, that has been modified with insulation, HVAC, electrical systems, windows, and entry doors to create a fully functional workspace. Container offices deliver to your site on a flatbed truck and can be placed on level ground, gravel, or a concrete pad within hours. They function as permanent or relocatable offices for job sites, farms, industrial operations, small businesses, and properties where traditional construction is impractical or cost-prohibitive.
How much does a shipping container office cost?
Our container office units start at approximately $100 per square foot fully outfitted, significantly less than traditional office construction, which runs $238 to $286 per square foot. A fully equipped 20ft container office provides 160 square feet of climate-controlled workspace, while a 40ft unit delivers 320 square feet. Pricing varies based on configuration, split layout options, and any additional customization. All Container One prices include delivery to your ZIP code with no hidden fees.

Container offices give you ownership rather than ongoing rental costs, building equity instead of paying lease fees. Corten steel construction is significantly more durable than the aluminum and composite materials used in most trailers, handling rough job sites, harsh weather, and frequent relocations without structural degradation. Container One backs every New 1-Trip office unit with a 10-year structural and 10-year no-leak warranty. Security is stronger, with 3-hour fire-rated entry doors, non-removable hinge pins, and security bars on windows. Container offices also hold resale value substantially better over time than trailers.
How long does delivery take for a container office?
Standard container office configurations deliver in 5 to 10 business days from order confirmation. Custom configurations, including split office and storage layouts, additional windows, or special electrical requirements, typically take 10 to 12 weeks from order to delivery. Container One ships from 300-plus U.S. locations, minimizing freight distance and delivery time regardless of where your site is located.
Can container offices be relocated after delivery?
Yes. Container offices can be lifted by crane or forklift and loaded onto a flatbed truck for transport to a new site, making them ideal for contractors and multi-site operations that move headquarters as projects shift. The destination site needs to be level and accessible by flatbed truck with roll-off or tilt-bed capability. We can assist with relocation logistics if needed.
Do I need a permit for a shipping container office?
Permit requirements vary by state, county, and municipality. In many rural and agricultural zones, a container office placed on your own property does not require a building permit, particularly when used as a temporary or mobile workspace. In commercial and residential zones, permits are more commonly required, especially for permanent placement or electrical hookups. Contact your local planning or zoning office before delivery. We provide full unit specifications, construction documentation, and warranty certificates that can support permit applications where required.
Are shipping container offices energy efficient?
Yes. Our office units use 2LB spray foam insulation at a 10.5 R-Value in walls, ceiling, and floor, comparable to or better than most modular office buildings. The 18,500 BTU HVAC system handles climate control efficiently for spaces of 160 to 320 square feet, and LED lighting reduces ongoing energy costs. For off-grid sites, the 50 Amp generator inlet allows the unit to run entirely on a portable generator without any grid connection.
How do I choose between a 20ft and 40ft container office?
A 20ft container office provides 160 square feet, sufficient for one to four people doing desk work, meetings, and file storage, with a compact footprint that fits tight job sites and farm yards. A 40ft unit provides 320 square feet for six to eight workstations or a combination of open office space and a dedicated meeting area. For operations that need both workspace and secure equipment storage in one footprint, the 40ft Office and Storage split divides the unit into a 10-foot office section and a 30-foot storage section with a partition door — eliminating the need for two separate structures.
